The zeros of the function f(x) = -(x + 1)(x - 3)(x + 2) are -1, 3, and -2, and the y-intercept of the function is located at (0,6)

<h3>The complete question</h3>

The zeros of the function f(x) = -(x + 1)(x - 3)(x + 2) are –1, 3, and __and the y-intercept of the function is located at (0,__)

<h3>How to determine the zeros?</h3>

The function is given as:

f(x) = -(x + 1)(x - 3)(x + 2)

Set the function to 0

-(x + 1)(x - 3)(x + 2) = 0

Divide both sides by - 1

(x + 1)(x - 3)(x + 2) = 0

Split

x + 1 = 0, x - 3 = 0 and x + 2 = 0

Solve for x

x = -1, x = 3 and x = -2

Hence, the zeros of the function f(x) = -(x + 1)(x - 3)(x + 2) are -1, 3, and -2

<h3>How to determine the y-intercept?</h3>

The function is given as:

f(x) = -(x + 1)(x - 3)(x + 2)

Set x to 0

f(0) = -(0 + 1)(0 - 3)(0 + 2)

Evaluate

f(0) = 6

Hence, the y-intercept of the function is located at (0,6)

At the movie theatre, child admission is $5.20 and adult admission is $9.70. On Sunday three time as many adult tickets as child
JulsSmile [24]

Answer:

23 child tickets were sold

Step-by-step explanation:

Using the information given, we can set up an equation to solve for the number of child tickets sold.  Since there were three times as many adult tickets as child tickets sold, we can assign the variable 'x' to represent the number of child tickets and '3x' to represent the number of adult tickets.  Since we know the cost of each ticket, as well as the total sales, we can set up the following equation:

5.20x + 9.70(3x) = 788.90

Simplify 5.20x + 29.1x = 788.90

Combine like terms:  34.3x = 788.90

Divide both sides by 34.3:  x = 23 child tickets

Interoperate your solution in the context of the problem.<br> f(10)=1.75r+9
iVinArrow [24]

Answer:

Simplifying

f(r) = 5 + 1.75r

Multiply f * r

fr = 5 + 1.75r

Solving

fr = 5 + 1.75r

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'r'.

f = 5r-1 + 1.75

Simplifying

f = 5r-1 + 1.75

Reorder the terms:

f = 1.75 + 5r-1
